A light emitting diode substrate includes a substrate, a plurality of first light emitting diode and second light emitting diode. The first light emitting diode are disposed on the substrate and arranged along a first direction and a second direction to form a first array. The first light emitting diode have a first side length extending along the first direction and a second side length extending along the second direction. The second light emitting diode are disposed on the substrate and arranged along the first direction and the second direction to form a second array. The second light emitting diode have a third side length extending along the first direction and a forth side length extending along the second direction. A first difference between the first side length and the third side length is less than a second difference between the second side length and the forth side length.
